According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):A flaw named FragmentSmack     was found in the way the Linux kernel handled     reassembly of fragmented IPv4 and IPv6 packets. A     remote attacker could use this flaw to trigger time and     calculation expensive fragment reassembly algorithm by     sending specially crafted packets which could lead to a     CPU saturation and hence a denial of service on the     system.(CVE-2018-5391)Multiple out-of-bounds write     flaws were found in the way the Cherry Cymotion     keyboard driver, KYE/Genius device drivers, Logitech     device drivers, Monterey Genius KB29E keyboard driver,     Petalynx Maxter remote control driver, and Sunplus     wireless desktop driver handled HID reports with an     invalid report descriptor size. An attacker with     physical access to the system could use either of these     flaws to write data past an allocated memory     buffer.(CVE-2014-3184)The __get_data_block function in     fs/f2fs/data.c in the Linux kernel before 4.11 allows     local users to cause a denial of service (integer     overflow and loop) via crafted use of the open and     fallocate system calls with an FS_IOC_FIEMAP     ioctl.(CVE-2017-18257)netetfilter/xt_osf.c in the Linux     kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for add_callback and     remove_callback operations. This allows local users to     bypass intended access restrictions because the     xt_osf_fingers data structure is shared across all     network namespaces.(CVE-2017-17450)A denial of service     flaw was discovered in the Linux kernel, where a race     condition caused a NULL pointer dereference in the RDS     socket-creation code. A local attacker could use this     flaw to create a situation in which a NULL pointer     crashed the kernel.(CVE-2015-7990)An issue was     discovered in the Linux kernel before 4.19.9. The USB     subsystem mishandles size checks during the reading of     an extra descriptor, related to

A local attacker could, in extremely rare     cases, use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-4608)It was found that Linux kernel's     ptrace subsystem did not properly sanitize the     address-space-control bits when the program-status word     (PSW) was being set. On IBM S/390 systems, a local,     unprivileged user could use this flaw to set     address-space-control bits to the kernel space, and     thus gain read and write access to kernel     memory.(CVE-2014-3534)A use-after-free flaw was found     in the Linux kernel's file system encryption     implementation. A local user could revoke keyring keys     being used for ext4, f2fs, or ubifs encryption, causing     a denial of service on the system.(CVE-2017-7374)The     usbip_recv_xbuff function in     drivers/usb/usbip/usbip_common.c in the Linux kernel     before 4.5.3 allows remote attackers to cause a denial     of service (out-of-bounds write) or possibly have     unspecified other impact via a crafted length value in     a USB/IP packet.(CVE-2016-3955)A flaw was found in the     patches used to fix the 'dirtycow' vulnerability     (CVE-2016-5195). An attacker, able to run local code,     can exploit a race condition in transparent huge pages     to modify usually read-only huge     pages.(CVE-2017-1000405)The aio_mount function in     fs/aio.c in the Linux kernel does not properly restrict     execute access, which makes it easier for local users     to bypass intended SELinux W^X policy     restrictions.(CVE-2016-10044)The Serial Attached SCSI     (SAS) implementation in the Linux kernel mishandles a     mutex within libsas. This allows local users to cause a     denial of service (deadlock) by triggering certain     error-handling code.(CVE-2017-18232)A use-after-free     vulnerability was found in tcp_xmit_retransmit_queue     and other tcp_* functions. This condition could allow     an attacker to send an incorrect selective     acknowledgment to existing connections, possibly     resetting a connection.(CVE-2016-6828)The instruction     decoder in arch/x86/kvm/emulate.c in the KVM subsystem     in the Linux kernel before 3.18-rc2 does not properly     handle invalid instructions, which allows guest OS     users to cause a denial of service (NULL pointer     dereference and host OS crash) via a crafted     application that triggers (1) an improperly fetched     instruction or (2) an instruction that occupies too     many bytes.
